THOMAS J. OOOKSON, OF CINCINNATI, OHIO.

STEAM-TRAP.

Specification of Letters Patent.

Patented Feb. 2, 1909.

Application filed February 23, 1904. Serial No. 194,672.

To all whom it may concern:

Be it known that I, THOMAS J. Common, a citizen of the United States of'America,

and resident of No. 2137 Grand street, Cin cinnati, in the county of Hamilton and State of Ohio, (post-office address No. 1112 Traction Buildin in the city of Cincinnati, county of Hami ton, and State of Ohio,) have invented an Improvement in'a Steam- Trap; and I do hereby declare the following to be a full and exact description thereof, reference being had to the accompanying drawings, making art of this specification.

My invention re ates to steam traps, and it has for its object the improvement in the construction of such devices whereby they are simplified and rendered more efficient in action.

The novelty of my invention consists in the combination and sub-combination of the parts, as will be hereinafter set forth and specifically pointed out in the claim.

Figure 1 is a longitudinal section of my steam trap. Fig. 2 is a section on line 2, 2, of Fig. 1 with the cap and interior mechanism removed. Fig. 3 is an end view of the cap, looking from the inside of the trap. Fig. 4 is a side elevation of the interior mechanism of the trap. Fig. 5 is a vertical section through the center of Fig. 4..

A represents the shell in which the mechanism of my trap is inclosed.

B is a cap which covers the o ening A of the shell A, to which it is attac ed by suitable cap screws. The inner side of the cap B has a shelf or projection B In the center of the cap is a tapped hole to receive the regulating device B By screwing the regulating device B in until it hits the tail piece 0 the o ening between chambers A and A is opened and the steam ermitted to blow through the trap; this is [or the pur ose of removing any grit which might co eat on the seat of the valve and thereby interfere with the proper working of the trap. After the objectionable material has been removed the regulating device is screwed back out of the way. The shell A is divided into two chambers, a large one A and a small one A Communication is had from the chamber A to the chamber A through the controlling mechanism 0 which is screwed into the tapped hole A The steam enters the trap through the tapped hole A and the condensed water which forms in the large chamber A passes from chamber A to chamber -water tight joint.

A through the valve port between them, and leaves the trap through either the tapped hole A or A whichever may be most convenient. A small hole A is tapped in the top of the trap for an air valve if one is desired. The regulating device B is an ordinary threaded stem provided with a stuffing box to prevent the leakage of steam.

The controlling mechanism 0 is composed of the following parts: There is a plug 0 which is screwed into the threaded hole A this plug C has a valve seat 0 screwed into the top of it. The outside of the upper end of the plug C is turned round and has clamped to it by a small screw C" a frame C the upper part of the frame C is rovided with a round hole C through w -ch the plunger C plays; the lower end of the plunger has screwed into it a plug C which conforms inshape with the valve seat C and when brought down so as to seat makes a" The u per side of the plunger C is ivoted to t e bell crank C The upper en of the frame 0 has attached to it an ear C to which the lower end of the link 0 is pivoted to the bell crank C". A hole C is tapped'into the bell crank in which a rod C is screwed; the opposite end of the rod from the bell crank has on it an ordinary float C The 0 eration of my device is as follows: Water ows in at the opening A until it raises the float C and as the float rises it causes the plug C to rise, permitting the water to run out through the plug G into the chamber A and from this chamber it passes out from the trap either by the opening A or A whichever is most convenient.

Some of the features of my trap which make it superior to ordinary traps are, the provision of aplate on which the water flows on entering the trap, so that any foreign matter that might be carried in by the water is not ermitted to fall onto the working parts of t e outlet, but diverted to one side and caused to fall to the bottom of the trap below the working parts, thereby reventing any grit from getting between t e plunger 0 and valve seat G which would cause the valve to leak, either by preventing it from seating by remaining on the seat, or cutting it in passing through with the water.

Another feature which traps do not ordinarily possess is the convenient way in which all the working parts can be removed from the shell A, which is as follows: The cap B is removed, the screw C loosened and all the Working parts can be removed by raising up the frame C, When it can be taken from the shell A. If the valve seat C or the plunger C should need grinding they can be easily removed by taking ofl the cap B and unscrewing them and putting others in their places, and no pipe connections are broken in removing any of the Working parts.

lVhat I claim is The combination in a steam trap, of two independent chambers, a large chamber, and

a small chamber, the large and small chambers automatically connected by a valve and float Within the large chamber, a st at iornrry plug between the large and small chamber to which is attached the frame which supports the valve mechanism, a clamp, and a screw C all substantially as described.
